Grenade — Factorio Production Calculator
Grenade is crafted in the assembling machine in 8 seconds, producing 1 per craft from 5 × Iron plate, 10 × Coal. At 60 per minute you need 16 assembling machines, and the chain behind it draws on 2 raw resources: coal, iron ore.
Production chain for 60 Grenade / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 300 | 16 | Furnace |
| Grenade | 60 | 16 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Coal | 600 |
| Iron ore | 300 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Grenade recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 8 s | 1 | Iron plate × 5, Coal × 10 |
What the whole chain needs
60 grenades per minute pulls in 1 intermediate product, and the whole tree comes to 32 machines across 2 machine types, fed by 2 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 600 per minute, which is 0.67 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses grenade
3 base-game recipes consume grenade, sorted by how much each one takes:
- Cluster grenade — 7 per craft
- Cliff explosives — 1 per craft
- Military science pack — 1 per craft
What grenade is made from
- Iron plate — 5 per craft
FAQ
How many assembling machines do I need for 60 grenades per minute?
16 assembling machines. One at standard speed produces 3.8 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does grenade take?
At 60/min the chain consumes 600 coal per minute, 300 iron ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is grenade needed for science packs?
Yes — it goes directly into Military science pack. Open the science pack page to see the demand that lands on this recipe.
